Samsung will be officially unveiling the new Galaxy S IV this Thursday. However, that's not stopping new images and details from leaking about the device ahead of the official unveil. New photos have turned up from China show a device that doesn’t mirror the design of previously leaked images.

However, the screenshots from the new leaked photos show that this device has hardware that matches up with previous leaks. This has led some to believe that this could be a prototype device used for carrier testing to protect the final design of the smartphone in the case of a leak (such as this one).

The screenshots show that the device is running Android 4.2.1 and has a full HD resolution 1080p display. The screenshots also show a 1.8 GHz processor, 2 GB of RAM, and a 13-megapixel rear camera.

The device in these new images is supposedly a dual-SIM version of the S IV destined for China Unicom.
